DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled fertilizer spreader for spraying fertilizer by centrifugal force of a rotary spreader,
The present invention relates to an improvement of a fertilizer spraying device having a fertilizer drop adjusting plate mechanism at a bottom of a fertilizer tank.

[0002]

2. Description of the Related Art Conventionally, a self-propelled fertilizer spreader that sprinkles fertilizer by centrifugal force while self-propelled, for example, as shown in FIG. A body frame 1 having a certain tail wheel 1c, a small engine 2 mounted on a rear portion of the body frame 1, and a forked steering handle 3a extending rearward from an upright vertical frame 3
(3b) and a fertilizer spraying device 4 mounted on the front part of the body frame 1, and the driving force from the small engine 2 is transmitted between the driving wheels 1a (1b) via a V-belt (not shown). To the transmission unit 5 (see FIG. 6), and is transmitted from the transmission unit 5 to the horizontal traveling axle 6 and the vertical distribution shaft 7, respectively. By operating the accelerator lever 7c, the engine speed changes, and the running speed of the fertilizer spreader can be varied.

Further, as shown in FIG. 6, a fertilizer spraying device 4 is fixed to a spraying shaft 7 via a boss 7a, and has a rotary spraying plate 9 having a plurality of spraying blades 9a, and a tank stand above the rotary spraying plate. Fertilizer tank (hopper) 15 fixed on plate 10
And a rod-shaped stirring member 12 fixed to a tip end of the spraying shaft 7 penetrating the bottom plate 15a of the fertilizer tank 15 with a fastening bolt (not shown) and rotating horizontally, and 1 or 2 formed on the bottom plate 15a of the fertilizer tank 15 2 or more fertilizer pits 15
b, and a disc-shaped shutter plate 11 having a fertilizer drop hole 11a aligned with the fertilizer drop hole 15b, being superimposed on the back surface of the bottom plate 15a of the fertilizer tank 15a and rotatable around the bearing 7b. Be prepared. The bottom plate 15a and the shutter plate 11 constitute a fertilizer drop adjusting plate mechanism.

Since the stirring member 12 in the fertilizer tank 15 rotates along with the bottom plate 15a with the rotation of the spraying shaft 7, the fertilizer (not shown) accumulated in the fertilizer tank 15 is continuously distributed without unevenness in the bottom plate. The fertilizer drop hole 15b of the shutter plate 11 is supplied to the fertilizer drop hole 15b and scraped off.
Since it continues to fall onto the rotating spray plate 9 via 1a,
Due to the centrifugal force of the scatter plate 9, the fertilizer is continuously scattered in a predetermined fan-shaped spray range (within a scatter angle). When the shutter operating lever 7d is operated, the shutter 11 rotates to turn the fertilizer drop hole 11a and the fertilizer drop hole 15b of the bottom plate 15a.
And the flow rate of the fertilizer that falls from the fertilizer tank 10a onto the rotary spray plate 9 can be adjusted.
It can be scattered. Also, one handle 3a
The spraying shaft 7 is operated by operating the accelerator lever 7c provided in (3b).
Can be varied, the centrifugal force of the rotary spray plate 9 can be increased or decreased, and the length of the fertilizer can be adjusted.

Incidentally, Japanese Patent Application Laid-Open No.
As in the fertilizer drop adjusting plate mechanism of the fertilizer spraying device described in Japanese Patent No. 298741, a second shutter plate having a fertilizer drop hole is provided under the shutter plate 11 in an overlapping manner, and the rotation position of the second shutter plate is set. It may be configured such that the direction of application of fertilizer can be changed by adjusting. This fertilizer drop adjusting plate mechanism is capable of adjusting the range and direction in which the fertilizer is spread by changing the flow rate and the drop position of the fertilizer using two shutter plates.

[0006]

After the fertilizer has been sprayed, it is necessary to remove the fertilizer remaining on the bottom plate 15a of the fertilizer tank 15 and clean it. Bottom plate 15a and shutter plate 1
This is because if the fertilizer (chemical fertilizer or the like) particles that are clogged in the gap between the fertilizer and the fertilizer are left, the shutter plate 11 hardly moves due to the deliquescence and viscosity of the fertilizer. However, the bottom plate 1
Although the fertilizer adhering to the surface 5a can be removed by wiping or washing when reaching into the tank 15, the fertilizer particles clogged in the gap between the bottom plate 15a and the shutter plate 11 are hardly removed. When the rotation of the shutter plate 11 is adjusted, the fertilizer grains also penetrate deep into the matching gap because they also act to bite the fertilizer into the matching gap.

Here, temporarily, the bottom plate 15a and the shutter plate 11
If the surface gap is set to be small by making the surface accuracy smooth, the rotation adjustment itself of the shutter plate 11 becomes inconvenient. In particular, in the fertilizer drop adjusting plate mechanism that also has the second shutter plate, the matching gap is doubled, so that the obstruction of clogging of fertilizer particles becomes a serious problem. In any case, the fertilizer tank 15 itself obstructs the cleaning of the fertilizer drop adjusting plate mechanism, and the bottom plate 15a is overlapped on the shutter plate 11, so that the shutter plate 11 and the second plate below the shutter plate 11 are disposed. It is impossible to clean the shutter plate itself.

In view of the above problems, the first aspect of the present invention
It is an object of the present invention to provide a self-propelled fertilizer spreader that can easily clean a fertilizer drop adjusting plate mechanism at the bottom of a fertilizer tank.

A second object of the present invention is to provide a self-propelled fertilizer spreader capable of easily removing a fertilizer clogging in a gap between plate mats of a fertilizer drop adjusting plate mechanism.

[0010]

Means for Solving the Problems In order to solve the above first problem, the first means adopted by the present invention is to provide a fertilizer drop adjusting plate mechanism on a tank table side to realize a fertilizer spraying device which can be easily disassembled. In which the fertilizer tank is pivotably hinged between a standing position and a sideways position so as to leave a part or the whole of the fertilizer tank.

[0011] That is, the present invention provides a rotary spraying means fixed to a spraying shaft, a fertilizer tank installed on a tank table for continuously dropping stored fertilizer on the rotary spraying means, and a bottom portion of the fertilizer tank. In a self-propelled fertilizer spreader provided with a fertilizer drop adjusting plate mechanism having a fertilizer drop hole, the fertilizer tank has an upright posture in which the bottom overlaps with the fertilizer drop adjusting plate mechanism. bottom Ru formed pivotably being hinged between the sideways posture state away from the manure falling baffle mechanism.

[0012] When cleaning the bottom of the fertilizer tank after spraying the fertilizer, the fertilizer tank is removed from the fertilizer tank, and when the fertilizer tank in the upright posture is pushed down, the fertilizer tank can be changed to the side-down posture. The adjustment plate mechanism is exposed. For this reason, the fertilizer tank is not in the way and the exposed fertilizer drop adjustment plate mechanism can be accessed very close,
Cleaning of the fertilizer drop adjusting plate mechanism as well as the tank bottom can be easily and carefully performed.

Further, in the present invention, the fertilizer tank has a bottom.

The shutter plate has a stirring member that rotates
Of a size that allows the body to pass through the stirring member in the axial direction.
It has a through hole.

[0014] Like a natural fall or a vibratory manure fall,
In a spraying device without a stirring member in the tank,
The fertilizer tank may be a bottomed hopper having a fertilizer dropping hole, but if the fertilizer tank is a bottomless hopper with a bottom opening, a fertilizer spraying device in which a stirring member is arranged in the fertilizer tank In this case, the agitating member can pass through the bottom opening without interference, so that the fertilizer tank can be changed to the sideways posture.

It is preferable that the fertilizer tank has a stopper for fixing the fertilizer tank to the tank base in the standing posture of the fertilizer tank. The standing posture of the fertilizer tank can be fixed, and the tank can be prevented from oscillating during spraying operation.

It is preferable that the fertilizer tank has a stationary base projecting from the bottom to the outer periphery. When the fertilizer tank is in the standing posture, the protruding stationary base abuts on the surface of the tank table, so that the load bearing strength is strong and the posture can be stabilized.

The turning axis of the fertilizer tank is provided between the tank base and the stationary base on one of the left and right sides in the traveling direction of travel, and the stopper is provided between the tank base and the stationary base on the other side. In this case, the fertilizer tank can be turned to the left or right. Of course, the turning axis may be provided at the front position in the traveling direction and the stopper may be provided at the rear position in the traveling direction so that the pivot can be turned sideways in the traveling direction.

[0018] It is preferable to provide a second stop between the rear position of the fertilizer tank and the handle side at a level above the stationary base. In addition to the fixing of the fertilizer tank by the above-mentioned stopper (first stopper), the fixing of the fertilizer tank by the second stopper is also added, so that the fixing force is increased and contributes to the stabilization of the posture. In particular, the second stopper is located substantially perpendicular to the center of the fertilizer tank from the first stopper, and the height of the stopper position is also changed, so that the tank can be effectively rolled or pitched. Can be suppressed.

Next, in order to solve the above-mentioned second problem, the means taken by the present invention is to provide a fertilizer drop adjusting plate mechanism with an adjusting plate itself which is easy to disassemble. A through hole having a size capable of passing in the axial direction with respect to the stirring member is provided.

That is, the present invention provides a rotary spraying means fixed to a spraying shaft, a fertilizer tank installed on a tank table for continuously dropping stored fertilizer on the rotary spraying means, and a bottom portion of the fertilizer tank. A self-propelled fertilizer spreader provided with a fertilizer drop adjusting plate mechanism having a fertilizer drop hole, wherein the fertilizer tank has a bottom opening, and the bottom opening is the fertilizer drop adjusting plate mechanism. The fertilizer drop adjusting plate mechanism is mounted on the tank base so as to be movable between a state in which the fertilizer drop adjusting plate mechanism is separated from the fertilizer drop adjusting plate mechanism, and a bearing through which the spraying shaft penetrates. And a receiving plate fixed to the tank base, and one or more shutter plates superposed on the receiving plate and rotatable around the bearing. Above tongue To protrusion provided et been in the inner has a stirring member which rotates, the shutter plate is itself composed of a slipping hole in the axial direction enables passing size with respect to the agitating member It is characterized by the following.

In the case of a bottomless fertilizer tank, the fertilizer tank is not limited to the case where the fertilizer tank is pivotally hinged as in the first means. It is possible to adopt a configuration in which the tank can be moved between a state in which it is covered and a state in which the bottom opening is separated from the fertilizer drop adjusting plate mechanism. The fertilizer drop adjustment plate mechanism left on the table side is exposed, so without removing the stirring member, disconnect the connection with the connecting link etc. connected to the operation part, and align the through hole of the shutter plate and the stirring member in the axial direction. By pulling out, the shutter plates can be separated and detached from each other or from the receiving plate part. Therefore, it is possible to individually clean the shutter plate and the receiving plate portion, and it is possible to easily eliminate clogging of the fertilizer drop adjustment plate mechanism in the plate matching gap. The shutter plate can be easily assembled.

FIG. 4 is a right side view showing the fertilizer spraying device, and FIG. 4 is a right side view showing an exploded state of a fertilizer drop adjusting plate mechanism in the fertilizer spreading device. 1 and 2, the same portions as those shown in FIGS. 5 and 6 are denoted by the same reference numerals, and description thereof will be omitted.

The self-propelled fertilizer spreader according to the present embodiment comprises a rotary spray plate 9 fixed to a spray shaft 7 and a bottomless fertilizer tank 25 installed on a tank base plate 10 and having a bottom opening 25a.
And a stirring member 12 that horizontally rotates so as to crawl on the bottom in accordance with the rotation of the spraying shaft 7 in the bottomless fertilizer tank 25, and a fertilizer drop adjustment installed on the tank base plate 10 under the bottom of the tank 25. And a plate mechanism 70.

The fertilizer tank 25 of this embodiment has a bottom opening 2
5a, the tank can pivot between an upright posture in which the bottom opening 25a overlaps the fertilizer drop adjusting plate mechanism 70 and a sideways posture in which the bottom opening 25a separates from the fertilizer drop adjusting plate mechanism 70. The base plate 10 is hinged with a hinge 30. The fertilizer tank 25 has a stationary substrate 25b that protrudes widely from the bottom opening 25a to the outer periphery.

In this embodiment, the hinge 30 is provided on the edge of the tank base plate 10 on the left side in the traveling direction, and is used for fixing the edge of the stationary board 25b to the tank base plate 10 in the upright posture of the fertilizer tank 25. The first hook hook 40 is provided on the right side in the traveling direction. Further, a second hook stopper 50 is provided between the rear portion of the fertilizer tank 25 and the handle portion at a level above the stationary board 25b. In the present embodiment, what is commonly called a “patch-in lock” is used as the hook hooks 40 and 50, which hooks a hook to a hooked portion and fixes the hook with a toggle mechanism. However, the invention is not limited thereto, and various types of stoppers (fixing means) may be used. However, according to the hook hooks 40 and 50, fastening or releasing operation is easy.

As shown in FIG. 3, the fertilizer drop adjusting plate mechanism 70 has a receiving plate portion 72 having a fertilizer dropping hole 72a and a bearing 7b into which the tank base plate 10 is shallowly recessed and the spraying shaft 7 penetrates. The bearing 7b is superimposed on the receiving plate 72.
, Which has a fertilizer drop hole 74a.
And a second shutter plate 76 superposed on the first shutter plate 74 and rotatable around the bearing 7b, and having a fertilizer dropping hole 76a. The first shutter plate 74 is provided with a through hole 74b having a shape and a size capable of passing through the stirring member 12 in the axial direction, in addition to the fertilizer dropping hole 74a. The second shutter plate 76 also has a through hole 76b having a shape and a size capable of passing through the stirring member 12 in the axial direction, in addition to the fertilizer dropping hole 76a. This through hole is opened at a position where the function of the fertilizer drop hole itself is not disturbed. The first shutter plate 74 includes an overhanging piece 74c, and a link plate 74e screwed with a screw 74d at the overhanging piece 74c.
Is connected to the standing pin 74g of the arm 74f connected to the shutter operating lever 7d so as to be able to be freely inserted and removed and connected in a pair. Similarly, the second shutter plate 76 also has an overhanging piece 76c.

In this example, the second (upper) shutter plate 76 can change the spraying direction, and the first (lower) shutter plate 74 can change the spraying range.

In the fertilizer spreader having such a configuration, when cleaning the bottom of the fertilizer tank 25 and the fertilizer drop adjusting plate mechanism 70 after the fertilizer is sprayed, the fertilizer remaining in the fertilizer tank 25 is taken out, and then the hook hooking device is used. When the fertilizer tank 25 in the upright posture is slowly tilted down by removing 40 and 50, the bottom opening 25a of the tank 25 passes through the stirring member 12,
As shown by the two-dot chain line in FIG. 2, the fertilizer tank 25 can be easily turned to the sideways posture. Although not shown, a stopper for holding the fertilizer tank 25 in a sideways position is provided in this example.

In such a state, the fertilizer tank 25 can access the fertilizer drop adjusting plate mechanism 70 remaining on the tank base plate 10 side without hindrance. Therefore, the tank bottom and the fertilizer drop adjusting plate mechanism 70 can be easily and carefully cleaned.

Further, since the shutter plates 76, 74 constituting the fertilizer drop adjusting plate mechanism 70 have the through holes 76b, 74b, the shutter plates 76, 74 are pulled out from the planting pins 76g, 74g, and the through holes are removed. The shutter plates 76 and 74 are separated from the receiving plate 72 as shown in FIG. 4 without removing the stirring member 12 by removing the stirring member 12 without removing the stirring member 12 by rotating the shutter plates 76b and 74b to a position just below the stirring member 12. Can be removed. Therefore, the receiving plate portion 72
In addition, since the shutter plates 74 and 76 can be separated and completely removed, individual cleaning can be performed, and clogging of the fertilizer in the gap between the plates can be easily eliminated. Note that assembling may be performed in the reverse order, so that assembling is also easy.

In this example, the fertilizer tank 25 is a stationary board 25b integrally projecting from the bottom opening 25a to the outer periphery.
Therefore, not only the standing posture of the fertilizer tank 25 is stabilized, but also the load bearing capacity can be increased. In addition, hinge 30
It is also useful for mounting.

Since the second hook hook 50 is located at about 90 ° from the position of the first hook hook 40 with respect to the center of the tank, the second hook hook 50 is placed on the tank base plate 10 of the tank 25 in the upright posture. Deviation can be effectively prevented. Further, since the second hook hooking member 50 is located at a level higher than the position of the first hook hooking member 40, the horizontal run-out of the tank 25 can be suppressed.

Although the present embodiment describes a fertilizer spreader used for spreading fertilizer, it is needless to say that the present invention can be used not only for spreading fertilizer but also for spraying a snow melting agent or an antifreezing agent on a road. Nor.
